Isn't it ironic that Newton, who created calculus and established the laws that govern the movement of all things, ushering in an era of science, was also fascinated by alchemy? Indeed, a 1979 chemical analysis of Newton's hair detected large quantities of mercury, a widely used alchemical reagent.
This further solidified Keynes's statement that Newton was the last magician.
At this point, it is necessary to find out what alchemy is, which even Newton was fascinated by.
Alchemy, simply put, is the secret art of turning cheap substances like iron and lead into expensive substances like gold and silver.
Since anyone can become rich overnight if they succeed, mankind has been desperately trying to discover this secret technique for about 2,000 years from ancient times to the Middle Ages.
People who once became immersed in alchemy often spent their entire lives melting, mixing, and separating substances day and night.

So how did she really survive? The air pressure in the air above the plane is extremely low.
So the airplane maintains a pressure control device inside the cabin.
However, if the plane is destroyed and the air pressure drops rapidly, the human body suddenly swells, and most people's hearts burst and they die instantly.
But Vesna Vulovic's heart was saved from bursting thanks to her chronic low blood pressure.
He was also trapped in the meal cart and crashed down a snowy slope with pieces of the broken aircraft.
The wide fuselage fragments increased air resistance.
It is not known exactly what angle of the slope she fell from, but even a 60-degree slope would have reduced the impact by half.
Also, if the snow had reduced the impact by more than half, survival would not have been impossible.

In 1988, a patient came to Dr. Pesmia at the University of Tennessee Medical School.
This patient had been hiccups at a rate of 30 times per minute for a whopping 72 hours.
It's impossible to hiccup for that long.
But there are people who have had hiccups for even longer than this person.
Charles Osborne, an American, is listed in the Guinness Book of World Records as the person who hiccups the most in the world.
He had hiccups for 68 years, starting in 1922.
This happens once every 1.5 seconds, a total of 430 million times.
Then, in 1990, when he was 96 years old, the hiccups suddenly stopped.
And he died the following year.
Dr. Pesmia tried every treatment available to the patient who came to him, but the hiccups did not stop.
In the end, the doctor used the last resort.
It's just putting your hand into the patient's anus.
But then, as if by magic, the hiccups stopped.
How could he stop hiccups?

Our body is made up of 7×1027 atoms.
American physicist Paul Ebersold says that 98% of this is converted into atoms from the air and food we consume within a year.
Also, according to researchers at the Weizmann Institute of Science in Israel, the total number of cells in our body is around 30 trillion, and we replace an average of 330 billion cells per day.
Every day, 1% of all cells change.
Epithelial cells renew themselves every 5 days, skin every 2 weeks, red blood cells every 120 days, liver every 2 years, bones every 10 years, and muscles every 15 years.
The only things that don't change throughout life are brain neurons and eye lens cells.
These two account for only 0.5% of all cells.
Therefore, whether from an atomic or cellular perspective, it is correct to view my body as a completely new body after 15 years.
This is no different from quantum copying, the only difference is whether it changes instantly or slowly.
Are you the same person you were 15 years ago and are you the same person now? What exactly am I? Is the self I perceive now an illusion? Does free will exist?

Contrary to Harry Houdini, there are people who believed in the existence of ghosts and tried to show that ghosts exist.
Thomas Edison, the inventor we all know so well.
Edison had over a thousand patents by the time he died.
But among the countless inventions he tried to make, there was one strange thing.
Before he died, he wrote a memoir called Reminiscences and Observations, and the story of this invention appears in the last chapter.
Edison thought it was very unscientific for mediums to sit at a table, place strange objects on it, and communicate with ghosts.
Edison decides to invent a scientific device to communicate with ghosts.
It is a ghost communication device that uses electromagnetic waves.
But there was a problem.
There was no way to verify that this was working correctly.
Edison made a solemn promise with his assistant, William Dinwiddie, that whoever died first would send a message from the afterlife.

As Carl Sagan pointed out, it was a huge mistake to think we had any presence in the solar system.
Wouldn't the solar system seen by aliens be nothing more than the sun? We're just a mere 0.14% impurity.
But this is wrong.
The various shapes and colors of diamonds, which are 99.95% carbon, are determined by the 0.05% impurities.
Electrons account for less than 0.03% of the mass of an atom.
However, all phenomena in the world that we experience, such as seeing, touching, and tasting matter, are caused by a few electrons located at the outermost part of atoms.

In 1971, Richard Keating and Joseph Hafel flew around the world twice, carrying four cesium atomic clocks on airplanes.
After the trip, a comparison with the four cesium atomic clocks kept on the ground showed that the clock on board was 59 billionths of a second slow.
This result was consistent with the predictions of the theory of relativity within a 10% error.
This also included time dilation in general relativity.
A few years later, physicists at the University of Maryland conducted a similar, more precise experiment.
They verified time dilation with an error of less than 1%.
Time dilation is also very essential for us today.
